Please send me the equations to find the relay time setting if they give the multiplier for difinite time, difinite minimum time and inverse difinite time

Dear Sir,

Pl. tell me how to calculate fault level of any electrical installation consisting of 1000Kva Transformer & Lt distribution system.
Regards,
Swapan.

Dear Sir,
I think this circuit diagram is incomplete. If any coil from c.t. or relay is open circuit,then circuit can not provide any protection.
For example-If Earth relay coil is open circuit,tripping shall not occurred,no protection shall offer.
In such case C.B.MUST NOT be close,more protective circuit is required.

Please guide me.

Thanks & Regards,
